“[T]he [PSA] test is hardly more effective than a coin toss [at detecting prostate cancer],” said Richard J. Ablin, PhD, a research professor of immunobiology and pathology at the University of Arizona College of Medicine and the president of the Robert Benjamin Ablin Foundation for Cancer Research, who discovered PSA (prostate-specific antigen) in 1970.

He wrote this in an Op-Ed in The New York Times in 2010 which was titled The Great Prostate Mistake.
